Description

Embedded plug connector

Technical Field

The present invention relates to an electrical plug-in connector, in particular for connection to an electronic circuit board.

Background

Such a plug-in connector, also referred to as a plug-in socket or a chassis socket, is also built into the switchboard, the distribution box or also into a wall of the device housing, mainly in the form of XLR, and is designed for connection to standard electrical circuits used in the entertainment industry. The standard circuit board can be provided in different embodiments, i.e. in different numbers and configurations of contacts and in different grounding and terminal arrangements and as a male plug and a female plug.

Three-to five-pin built-in sockets are also known in the form of embodiments for connection to horizontal circuit boards. The electrical contacts of these embodiments are guided out at one end of the housing parallel to the longitudinal axis of the housing and then extend in a bent manner, wherein the connection regions for the circuit boards end in a common plane parallel to the longitudinal axis of the housing. Here, the connection region can also be located on the outside of a plate-like element. If more data or power channels are needed, the embedded socket may no longer be used.

On the other hand, XLR connectors of the 8+2 type are known, which provide two energy channels in addition to eight data channels. Due to the presence of a plurality of contacts which are led out at the rear end side, the connection to the circuit board can only be realized in a vertical arrangement, in which case the circuit board is oriented parallel to the rear end side of the housing and thus transversely to the longitudinal axis of the housing. As a result, no connection to a horizontally arranged circuit board is possible, which limits the field of use of such plug connectors.

SUMMERY OF THE UTILITY MODEL

The object of the invention is a plug connector with a large number of data or energy channels, which plug connector is furthermore suitable for connection with a horizontally arranged circuit board.

In order to solve this problem, an electrical plug-in connector is proposed, which has a housing and more than five electrical contacts which are fixed in the housing and which are led out at one end of the housing parallel to the longitudinal axis of the housing. The end sections of the contacts located outside the housing are bent in relation to their sections located inside the housing and their connection regions intended for connection to the circuit board end in a common plane, which is parallel to the longitudinal axis of the housing.

The plane is preferably radially further outward than a tangential plane of the housing parallel to the plane.

The connection regions of the sections of the contacts which extend at an angle and preferably perpendicularly to the longitudinal axis of the housing are arranged in groups, each group lying on at least three parallel straight lines which are part of the common plane in which the connection regions end.

The difficulty of turning the contacts from a direction parallel to the longitudinal axis of the housing to a direction bent in relation to the longitudinal axis can be overcome by the end sections of the contacts which are led out of the housing in parallel having the same distance in the direction of the longitudinal axis of the housing as the parallel straight lines. In this way, a staggered position of the turning points from the parallel direction to the bending direction along the longitudinal axis of the housing is obtained, which provides sufficient positions for the contactless arrangement of the bent sections of the contacts and the distribution of the bent sections of the contacts that are sufficiently spaced apart from one another.

Preferably, eight contacts for data transmission and two contacts for energy transmission are provided in order to comply with the standard configuration.

It is expediently provided here that the contacts for the energy transmission have a larger diameter than the contacts for the data transmission. In this way, a high current density can be transmitted for sufficient power supply, while a small wire cross section is sufficient for data transmission operating at low voltages and current densities, so that a large number of wires can be provided per socket.

In one embodiment, the contacts are fixed in contact carriers which are inserted into the housing parallel to the longitudinal axis of the housing, which makes it possible to use one housing type for a large number of switching schemes and thus for different plug-in sockets.

A particularly advantageous embodiment for fixing the contact carrier in the housing provides that the contact carrier is fixed by means of a holding element in the housing on the side of the housing from which the contacts are led out on the outside of the housing.

Such an embodiment is preferred and simple to handle, wherein the retaining element is a ring structure which at least partially overhangs the housing wall inwardly and is connected to the housing wall at least one point.

When the retaining element and the housing wall are crimped to one another in at least one position, a reliable connection between the retaining element and the housing can be established simply and quickly.

The plug connector is designed as a preferred embodiment of a male plug, the electrical contacts being designed as contact pins.

In contrast, the electrical contacts are designed as at least annular contact openings for the design of the plug-in connector as a female plug.

Since the plug-in connector according to the invention is to be fastened to a power distribution panel or in an equipment housing, according to a first embodiment it is provided with a mounting structure, which is at least one laterally projecting lug with a mounting hole. Two lugs are usually provided, which are opposite one another with respect to the central axis of the housing.

Another very advantageous, at the same time very stable solution provides that the mounting structure is a flange which overhangs the entire circumference of the housing, in which flange at least one mounting hole is machined. Here, too, at least two mounting holes are provided in the flange, which mounting holes are opposite one another with respect to the center axis of the housing. Here, the flange may have a rectangular shape or may also have a circular or flange-like shape.

According to a preferred embodiment of the plug-in connector, the bent-over sections of the contacts extend straight and are parallel to one another over a large part of their length. This allows the necessary spacing of the conductive elements from one another to be achieved while the design is simple.

In order to facilitate the mounting of the plug-in connector, in particular of the contacts thereof, the angled section is a separate component, that is to say is not integrally formed with the contact which is accommodated in the housing and which is led out through the contact carrier, and is directly connected to the section of the contact which is led out to the outside of the housing. This can be achieved by screwing, riveting or also by welding and at least also by gluing with an electrically conductive adhesive.

In order to ensure that a precisely defined geometric arrangement of the connection regions relative to the circuit board is achieved, the bent-over sections are fixed in a common holding plate shortly before their connection regions. The retaining plate is preferably also arranged radially outside the parallel tangential planes of the housing.

The common holding plate can also have an extension which extends flush along the housing in order to ensure a tight fit and a good connection to the circuit board on the one hand, but also to connect the holding plate to the housing in a better and mechanically fixed manner on the other hand. For this purpose, guide or stabilizing arrangements can be provided in or on the housing and in the extension of the holding plate, which engage in one another.

Detailed Description

It should be noted that, in the case of differently described embodiments, identical components have the same reference numerals or the same component names, and the disclosure contained in the entire description can be transferred reasonably to identical components having the same reference numerals or the same component names. The positional references selected in the description, such as, for example, upper, lower, lateral, etc., relate to the currently described and illustrated figures and can be transferred to the new position in a rational manner when the position changes.

All statements as to numerical ranges in the specification should be understood to include any and all subranges therein, such as statements 1 to 10, to include all subranges beginning with a lower limit of 1 or more and ending with an upper limit of 10 or less, such as 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.

To comply with the regulations, it is finally pointed out that the manufacturing apparatuses or their components are sometimes not shown to scale and/or enlarged and/or reduced in order to better understand the structure of the elements.

The electrical plug-in connector shown in the figures as an example in the form of a plug-in socket of the 8+2 type which can be connected to an electronic circuit board has a housing 1. The housing may be made of plastic, but may also be made of a metallic material.

On the front end side, i.e. on the insertion side of the complementary cable connector, a rectangular or square mounting flange 2 is provided as a mounting structure which projects transversely to the longitudinal axis a of the housing 1. Mounting holes 3 are formed in two opposite corners of the mounting flange 2 with respect to the longitudinal center axis a, in order to be able to fasten the plug-in socket to a switchboard, a wall of an appliance or the like by means of mounting screws, rivets or the like which pass through the mounting holes 3. The mounting flange 2 can also be designed round, oval, with any polygonal circumferential edge or in a similar manner. Alternatively, mounting lugs with holes projecting laterally from the cylindrically shaped housing 1 can also be used, in which case two lugs opposite one another with respect to the longitudinal axis a of the housing 1 are preferably provided.

The housing 1 in the exemplary embodiment shown as a male plug encloses a total of 10

contacts

4, 5 designed as contact pins. These contacts are held in contact holders 6 (see fig. 3 and 4) which are manufactured separately from the housing 1 and are inserted into the housing parallel to the longitudinal axis a of the housing 1. The contact mount 6 is made of an electrically insulating material, in particular plastic, and exposes an end section of the plug connector which points to the complementary. In the case of the embodiment of a female plug, the contact carrier 4, which in this case extends entirely up to the front end of the housing, receives an annular or cylindrical contact element.

In the case of the type 8+2 embodiment of the plug-in connector described here, two contacts 4 for energy transmission and eight contacts 5 for data transmission are provided. The contacts 4 for the energy transmission are preferably designed here with a larger diameter than the thinner contacts 5 for the data transmission.

The

contacts

4, 5, in this case contact pins, extend parallel to the longitudinal axis a of the housing 1 and are guided out on the rear side of the contact carrier 6 or on one end of the housing 1 or also through the two

components

1, 6, likewise parallel to the longitudinal axis a of the housing 1, and project out of the housing 1 on the end side thereof opposite the insertion side for the cable plug.

The

end sections

41, 51 of the sections of the

contacts

4, 5 located outside the housing 1 are bent over relative to the sections of the contacts located inside the housing 1. The

end sections

41, 51 extend generally transversely to the longitudinal axis a of the housing 1 and also extend parallel to one another at least from a determined distance from the

contacts

4, 5. The end sections transition at their outermost ends into

connection regions

42, 52 provided for connection to an electronic circuit board. The connecting regions terminate in a common plane E parallel to the longitudinal axis a of the housing 1 and preferably also outside the envelope circumference of the housing. The

connection regions

42, 52 are arranged in groups, wherein the groups lie on at least three straight lines G (see fig. 4) which are part of the common plane E, as is best shown in fig. 4 and 5. In fig. 5, these straight lines G run through the

connection regions

42, 52 perpendicular to the drawing plane.

The

end sections

41, 51 can be designed as direct extensions of the

contacts

4, 5 and can be turned by crimping or bending from a direction parallel to the longitudinal axis a into a direction transverse to the longitudinal axis and parallel to each other. However, the embodiment shown in the figures is preferred, in which the bent-over

end sections

41, 51 are produced as separate elements, which are then connected directly, for example by riveting, to the sections of the

contacts

4, 5 which lead out of the housing, as can be seen in the figures. The

end sections

41, 51 are preferably designed as flat metal strips, in which case the

connection regions

42, 52 preferably have a smaller width than a large part of the length of the

end sections

41, 51.

The bent-over

end sections

41, 51 of the

contacts

4, 5 are fixed in front of their

connection regions

42, 52 in a common holding plate 9, from which the

connection regions

42, 52 project on the side facing the circuit board in order to be able to be connected thereto. The common holding plate 9 is preferably provided with an extension 91 extending along the housing 1, which together with the holding plate 9 achieves a close fit and good connectability to the circuit board and also ensures a mechanically stable connection between the housing 1 (and the circuit board) and a precisely defined position of the

connection regions

42, 52.

The ends of the sections of the

contacts

4, 5 which are parallel to one another and to the longitudinal axis a and which emerge from the housing 1 preferably have the same spacing in the direction of the longitudinal axis a of the housing 1 as the parallel straight lines G and vice versa.

The contact carrier 6, which is preferably inserted into the housing 1, is fixed on the side of the housing from which the

contacts

4, 5 are led out on the outside thereof by means of a holding element, which is preferably designed here as a ring structure 7, in the housing. The ring structure 7 is designed here to project at least partially inwards beyond the inner end side of the wall of the housing 1, where it overlaps the rear end side of the contact carrier 6 and thus prevents the contact carrier from being able to be pushed out of the housing 1 backwards. For this purpose, the ring structure 7 is fixedly connected to the housing 1 in at least one location. This connection can be established by the crimped connection of the radially outwardly projecting tongues 71 of the ring structure 7, which are guided between the two tenons 8 of the housing 1, with said tenons 8.

The front insertion opening in the housing 1 preferably has a cutout 21 at least one peripheral position, which extends parallel to the longitudinal axis a of the housing 1 back into the interior of the housing. The contact carrier 6 may also have recesses 61 at corresponding locations. The cutout 21 and the recess 61 serve as a receptacle for a locking mechanism 10 of known design, which is schematically illustrated in fig. 2.

The examples show possible embodiments, wherein it should be noted here that the invention is not limited to the specifically shown embodiments themselves, but that different combinations of the individual embodiments with one another are also possible and that such solution possibilities are understandable to the person skilled in the art on the basis of the teaching of the invention to technical means.
